zhannawk [14.2K]

Answer: B. development of female sex

Development of female sex characteristic is not associated with the amount of cortisol in the body.

Explanation:

Cortisol is a steroid hormone secreted by the adrenal gland. It facilitates stress response, regulates blood sugar level and helps fight infections. High cortisol level leads to Cushing syndrome and low cortisol level leads to Addison disease.

Obesity is a  symptom of Cushing syndrome while weight loss is a symptom of Addison disease. Thus levels of cortisol can affect body weight as well.  When in a stressful situation, our body pumps excess cortisol.

Cortisol level in our body is generally high in the mornings and low in the midnight.

A 0.20 kg mass attached to the end of a spring causes it to stretch 3.0 cm. What is the spring constant? What is the potential e
SVEN [57.7K]

Given that the mass is m = 0.2 kg and the displacement is x = 3 cm = 0.03 m

We have to find the spring constant and potential energy.

The spring constant can be calculated by the formula

\begin{gathered} F=\text{ kx} \\ mg\text{ = kx} \\ k\text{ = }\frac{mg}{x} \end{gathered}

Here, k is the spring constant.

g = 9.8 m/s^2 is the acceleration due to gravity.

Substituting the values, the spring constant will be

\begin{gathered} k=\frac{0.2\times9.8}{0.03} \\ =\text{ 65.33 N/m } \end{gathered}

The potential energy can be calculated as

\begin{gathered} U=\frac{1}{2}kx^2 \\ =\frac{1}{2}\times65.33\text{ }\times(0.03)^2 \\ =\text{ 0.0293 J} \end{gathered}
